Portable Hammond Organ A electric guitar pickup is actually similar to a vibrant mike coil. For many years, dynamic microphones have been wired with the voice coil attached to the primary of the microphone's transformer, and maybe not called to ground (‘floating'). The microphone's case is usually attached to the wire guard, which is attached to the mike amplifier's floor (see Rane's web site for more discussion).
By and large, vibrant microphones are very quiet products consequently of the combination of transformer isolation and balanced, hanging transmission lines throughout, along with shielded, humbucking coils.
So why not instruments? Guitars are notoriously overwhelmed by noise. Humbucking pickups are just an incomplete (though important!) solution. The most obvious option would be to float the guitar pickup to a healthy production, being a microphone. The same thought was printed that 2001 patent software like this Portable Hammond Organ?
